摘　　要：目的了解浙江省江山市江郎山景区主要病媒生物种类、密度、季节消长情况,为山川型景区病媒生物防制提供科学依据。方法根据《浙江省病媒生物监测工作方案》要求,2019-2021年在江山市江郎山景区开展小兽、蚊类和蜱监测;其中小兽监测采用夹夜法,成蚊监测采用诱蚊灯法,幼蚊监测采用布雷图指数(BI)法,蜱采用动物体表检蜱法和布旗法。采用描述流行病学方法分析不同环境的病媒生物种类构成、密度情况和消长趋势。结果2019-2021年江山市江郎山景区小兽总密度为5.76%,优势种为黑线姬鼠,占48.10%。采集171份小兽肺标本进行汉坦病毒抗原检测,阳性率为2.34%(4/171);采集171份小兽血标本进行汉坦病毒抗体检测,阳性率为2.92%(5/171)。蚊类监测优势种为淡色库蚊/致倦库蚊,占73.46%,其次为白纹伊蚊、骚扰阿蚊和中华按蚊,2019-2021年平均BI值为17.83。未捕获到蜱虫。结论江郎山景区以黑线姬鼠为捕获小兽优势种,淡色库蚊/致倦库蚊为优势蚊种,应采取综合性防控措施以控制病媒生物孳生及相关传染病的传播流行。Objective To investigate the main species,density,and seasonal variation of vectors in Jianglang Mountain scenic area,Jiangshan,Zhejiang Province,China,so as to provide a scientific basis for vector control in mountain and river scenic areas.Methods According to the Zhejiang Province Vector Monitoring Work Plan,small mammal,mosquito,and tick surveillance were carried out in Jianglang Mountain scenic area,Jiangshan from 2019 to 2021.Small mammal surveillance was conducted using the night trapping method,adult mosquito surveillance using the mosquito trap lamp method,mosquito larva surveillance using the Breteau index(BI)method,and tick surveillance using the tick inspection on the body surface of animals and the drag-flag method.The descriptive epidemiology was used to analyze the species composition,density,and variation trend of vectors in different environments.Results The small mammal density in Jianglang Mountain scenic area in Jiangshan from 2019 to 2021 was 5.76%,with the dominant species being Apodemus agrarius,accounting for 48.10%.A total of 171 small mammal lung specimens were collected for Hantavirus antigen detection,with a positive rate of 2.34%(4/171);171 small mammal blood samples were collected for Hantavirus antibody detection,with a positive rate of 2.92%(5/171).The dominant species of mosquitoes were Culex pipiens pallens/quinquefasciatus,accounting for 73.45%,followed by Aedes albopictus,Armigeres subalbatus,and Anopheles sinensis.The mean BI value from 2019 to 2021 was 17.83.No tick was captured.Conclusions The dominant species of small mammals in Jianglang Mountain scenic area is A.agrarius,and the dominant species of mosquitoes is Cx.pipiens pallens/quinquefasciatus.Comprehensive prevention and control measures should be taken to control the breeding of vectors and the spread of related infectious diseases.
